Energy efficiency has become a major focus for our government, municipalities as well as power utilities and the industrial sector. Each entity has a specific area where they focus their attention. In every case attention was directed to components, i.e. motors, pumps....

When building a motion drive or controller, manufacturers traditionally implement advanced control techniques and package them in a black box with a few gain settings, a slider, or an autotuning feature, and the machine builder or end user may never know or care how the control is implemented....

Imagine being a prospective student interested in attending East Carolina University arriving at the sprawling Greenville, North Carolina campus with your parents in tow and eager to take a look around. Suddenly, two doors on the library’s giant clock tower open up....

In the case of long-term infrastructure planning, it is essential to consider how network function virtualization (NFV), will impact and enable data centers in the next five to 10 years. NFV is an ideal alternative to traditional networking solutions, as it allows organizations to upgrade infrastructure....

In any modern day multi-processor based system, bus interconnects are one of the most complex IP blocks. All these system bus-interconnects are the backbone of the whole system for end to end communication, carrying substantial transaction bandwidth across the chip....

IGBTs are commonly used in inverter systems, which are used for adjustable motor drives, solar inverters and UPS. Inverters can be single-phase or three-phase, which is basically an extension of the H-bridge. Figure 1 illustrated one of the six gate driver optocouplers from Fairchild Semiconductor driving the IGBT module for the implementation of the three-phase inverter system.

When I hear or read the phrase wind power, I immediately imagine tall-towered machines with tri-blade impellers tracing out huge arcing sweeps against partly cloudy skies. Your imagery may vary. Globally, wind generation capacity climbed to 318 GW in 2013 and has increased, year-over-year, an average of 37 MW since 2008....

Engineering these days has a tendency to cross disciplines more than ever. Decades ago, companies started using medical technologies (radiography to be exact) to inspect solid structures and mechanical parts ...

Organizations are losing money simply because they are not looking critically at the interconnect technology choices they have. Why? Because they are too wed to Ethernet and InfiniBand to acknowledge that these two are no longer the most economical technologies in system connectivity.

Vision systems are playing an increasingly important role on the battlefield. Prized for their ability to improve surveillance while keeping troops out of harm’s way, these systems are becoming the vital electronic “eyes” in a growing range of military operations....

Twenty years ago, I worked for a flexible circuit manufacturer supplying to automotive instrument panel manufacturers. At that time, these manufacturers were wary of LED lighting. The tried and true twist-in bulb represented 99.9% of interior and exterior automotive lighting....

Imagine being surrounded by the imagery of your dreams on a panoramic display. Now imagine being able to manipulate these images by pointing directly at them, like a conductor leading an orchestra of pixels. It sounds like something straight out of a science fiction film — which is exactly what it is....

We are living in an exciting time of change. The era of cloud computing has come upon us over the last few years bringing profound changes in the way we conduct our day to day lives. We are seeing a lot of changes in the way traditional high performance computing (HPC) applications are developed and deployed....

With use of the cloud comes the ability to use as many resources as needed, essentially endless resources on demand, using a “pay-as-you-go” model. In a world where everything is dynamic and IT environments are constantly changing, this is becoming an ever-growing necessity....

This is a golden age of innovative electronics. Lowered barriers to entry for innovators in the form of lowered costs, funding, and more ubiquitous manufacturing options are making it much easier for anyone with a good idea to become an entrepreneur. So what does all this have to do with cloud-based product lifecycle management (PLM)?
